89 Suburban won't start

alarman · 2004-01-18T04:08:38+00:00

Hello, group:I have a 1989 Chevy Suburban, 350TBI. It's run like a top for the 5 yearsI've had it. Suddenly it won't start. It cranks, but won't turn over. NowI know it's either no spark or no fuel, right? Plenty of gas in the tank.My questions are how to properly check for spark? I don't want to screwsomething up, and I don't want 20,000 volts either. If I have spark, what'snext? The fuel pump? Where is it, and how difficult is it to replace?Thanks in advance for any help.

At least yours wasn't UTTER stupidity! "Why wont this frikken U-joint pop out! I have the clamps all the way off" "S*it she be rollin!"

Good thing my father drilled into my head "always know where your going to be going if something goes bad." I was able to get out, and then I had to run after the truck and stop it before it hit a tree. I stopped with about 1/16 of an inch to spare (literally).

I always put a tire under the truck. I was always tought, jack it up and put uncrushable s*it under it. We have an old steely and an 8x8 that work well. I mean, even when I change a tire I always have at least one tire underneath the frame.

Very excited though, just sprang for a 3ton (21" lift) Mack (as in the truck) floor jack, and four 6ton Mack jack stands. $120.00

OK, I got back to the Burb today. AutoZone did test the module, and it passed. Now I know you said not to throw parts at it, but: 1. knowing that electronic devices sometimes test OK when they are not, and 2. being naturally curious, I went ahead and replaced the module. Bzzzzzzz. I lose. It still won't start. So, I am at a loss. I guess I'll have it towed to the shop next week. Sure wish I could pinpoint the trouble. Thanks to all who tried to help. I'll post back when I find out what happened. Jack
